Description

Comprehensive small farm wheel excavator

One. technical field: the utility model relates to agricultural wheel excavator, promptly a kind of comprehensive (360 °) small farm wheel excavator.

Two. background technology: in the prior art, 1, center of gravity is unreasonable.It is rear-mounted that the agricultural grab swing arm belongs to walking, and after center of gravity was inclined to one side, the place ahead was too light when vehicle advanced, and walking stability is relatively poor, along with the wearing and tearing of arm cover, makes front of digging machine too big to steering mechanism's swing, and safety factor reduces; And the long excavation of vehicle body turns to work very inconvenient.2, operation easier is big.Because existing excavator turntable can only rotate 180 ° of corners, haulage vehicle must be positioned over the operative end surface edge, in case there is carelessness vehicle will be slipped in the hole slightly, promptly uses excavator that vehicle is sling, and also difficulty is placed into vehicle on the level land of end face; More than 1.5 meters, if dig deeply more than 1.5 meters, the operator can't see the scraper bowl working condition to the driver's cabin form of excavator so, not only influences operating efficiency apart from hole ground work plane, and easily cause excavate improper.3, turntable structure is unreasonable.Existing turntable is to finish by the reciprocal operation of oil cylinder of two series connection, and impact phenomenon is serious, and the oil circuit that has can't be installed buffer, the installation cushion dashpot that has, and turntable can not rigidity be located, and makes free movement excessive, and the dynamic duty positioning performance is relatively poor.

Three. technology contents:

This uses novel technical problem to be solved is to overcome the weak point that exists in the above-mentioned background technology, reaching is a kind of comprehensive rotation small farm wheel excavator, increase work efficiency and security performance, enlarge the digging operation scope, purpose swift and convenient to operate.

The novel technical solution of this use is as follows: a kind of comprehensive small farm wheel excavator, basically go up assembling device for revolving and driving (7) by the vehicle frame that has hydraulic leg (1) (2), engine pack (9), the bucket assembly is formed, it is characterized in that: in the device for revolving and driving (7), base middle part on the vehicle frame (2) is turntable main shaft (11) fixedly, main shaft (11) periphery bearing (25) assembled shaft bearing (14), bearing support (14) periphery is turntable (10) fixedly, main shaft (11) top connects swivel coupling (17), fixed support plate (24) above the turntable (10), operating room (8) and mekydro electric machine assembly, in this mekydro electric machine assembly, can control motor (23) the output driving gear (26) and fixed gear ring (20) engagement of rotation, gripper shoe (24) goes up the controllable bucket assembly of assembling.

Described comprehensive small farm wheel excavator is characterized in that: in the base on the vehicle frame (2), axle bearing plate (12), channel-section steel (15) and root plate (13) are fixed as a unsplit bedplate successively.

Described comprehensive small farm wheel excavator, it is characterized in that: in the swivel coupling (17), with on the swivel coupling axle (31) that main shaft (11) connects two independently height hydraulic oil cannelure (35) and corresponding holes (34) are arranged, socket opening steel loop (32) between cannelure (35) groove, form energy storage oil transportation sealing mechanism by the swivel coupling overcoat (30) that the last socket of swivel coupling axle (31) has lid (29), swivel coupling overcoat (30) has two holes corresponding with the inside two cannelures (35), and swivel coupling overcoat (30) outside is connected with gripper shoe (24).

Described comprehensive small farm wheel excavator, it is characterized in that: in the described mekydro electric machine assembly, motor (23) by brake disc (22) fine setting, turntable brake (27) control connects driving gear (26) through reductor (21), and the gear ring (20) that is meshed with driving gear (26) is fixed on the datum axle bearing plate (12).

Described comprehensive small farm wheel excavator is characterized in that: in the bucket assembly, gripper shoe (24) goes up the hinged swing arm (5) that has oil cylinder, the hinged dipper (3) that has oil cylinder of swing arm (5), the hinged bucket (4) that has oil cylinder of dipper (3).

Described comprehensive small farm wheel excavator is characterized in that: bearing support (14) is gone up the following fixedly accessory plate (16) of the turntable (10) that connects.

Described comprehensive small farm wheel excavator is characterized in that: operating room (8) is formed a closed service depot by openable door, window and fixing ledge.

Advantage and effect that this use is novel are as follows: 1. be assemblied on the turntable owing to whole operating mechanism, so Excavating bucket can rotate 360 °, improved excacation efficient, enlarged job area, can dig dark 2.8 meters through trial-production, 0.4 meter 3 of bucket capacity lifted high 5.1 meters, 3.3 meters of discharge heights, 7 meters of operative end surface fabric widths (the steady job width of disposable displacement).2. volume is little, and 3.4 meters of comprehensive excavator running lengths are than 2.4 meters of original shortenings.3. transverse shift fast; Drive without the driver, and pulling turntable control crank plays liftoff displacement with swing arm with car one crown, the swing arm of migrating again after the displacement is used the liftoff displacement of car other end jack-up with quadrat method and is back and forth carried out, with the car transverse shift.4. invar spare welding, so overall construction intensity is big, turntable and fuselage stability strengthen.5. owing to adopt the opening steel loop to replace rubber ring, so its gap is very little, leakage rate is no more than 0.5%, the possibility of having avoided hydraulic oil to puncture, durable in use, the withstand voltage 40-50 MPa (400-500 kilogram) that reaches, both economical, simple again, this is another novel characteristics of this use.6. compact conformation, cost low (about 3.1 ten thousand yuan), usability is strong, peasant household easily accepts, driver's cabin can assemble air-conditioning, be one both high-grade, economical and practical again, the desirable comprehensive rotation small farm wheel excavator that operating efficiency is high again.
